Version: 2.4.22
OS: Red Hat Enterprise Linux 5 update 5 64-bit
URL: ftp://ftp.openldap.org/incoming/
Submission from: (NULL) (132.198.107.64)


Platform: Red Hat Enterprise Linux 5, update 5, 64-bit
OpenLDAP: 2.4.22 (locally compiled), configured with delta-syncrepl.

The following modify ldif successfully applies to the master:

dn: uid=fcswasey,ou=People,dc=uvm,dc=edu
changetype: modify
replace: sn
sn: Swasey
-
replace: sn
sn: Swasey
-

In OpenLDAP 2.3 -- this modify ldif deck failed because the "sn"
attribute is presented twice.  In OpenLDAP 2.4 -- it works, but the
delta-syncrepl replica pukes on it with this error:

syncrepl_message_to_op: rid=100 mods check (sn: value #0 provided more
than once)
